Production of deuterons, tritons, 3He nuclei, and their antinuclei in pp collisions at √s = 0.9, 2.76, and 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Invariant differential yields of deuterons and antideuterons in pp collisions at √s = 0.9, 2.76 and 7 TeV and the yields of tritons, 3He nuclei, and their antinuclei at √s = 7 TeV have been measured with the ALICE detector at the CERN Large Hadron Collider. The measurements cover a wide transverse momentum (pT) range in the rapidity interval |y| < 0.5, extending both the energy and the pT reach of previous measurements up to 3 GeV/c for A = 2 and 6 GeV/c for A = 3. The coalescence parameters of (anti)deuterons and 3He nuclei exhibit an increasing trend with pT and are found to be compatible wi ...Daha fazlası

Dielectron production in proton-proton collisions at s√ = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The first measurement of e+e− pair production at mid-rapidity (|ηe| < 0.8) in pp collisions at s√=7 TeV with ALICE at the LHC is presented. The dielectron production is studied as a function of the invariant mass (mee < 3.3 GeV/c2), the pair transverse momentum (pT,ee < 8 GeV/c), and the pair transverse impact parameter (DCAee), i.e., the average distance of closest approach of the reconstructed electron and positron tracks to the collision vertex, normalised to its resolution. The results are compared with the expectations from a cocktail of known hadronic sources and are well described when ...Daha fazlası

A Novel EOG-Based Wireless Rapid Communication Device For People With Motor Neuron Diseases

UŞAKLI, Ali Bülent | GÜRKAN, Serkan | GÜRKAN, Guray | KAYA, Alper

In this study, a new electrooculography (EOG) based system that provides efficient communication for people suffered from motor neuron diseases is presented. The system consists of two distinct devices. The first device operates as a main unit that is activated by the subject’s eye movements. This unit is capable of transmitting 10 different command/state messages. These messages enable subject to choose his/her situation such as “I’m fine”, “I feel bad”, “I’m hungry” and “I’m thirsty”. Commands such as “Come”, “Go”. The number of messages can be increased. The main unit acquires the EOG signa ...Daha fazlası

Medium modification of the shape of small-radius jets in central Pb-Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present the measurement of a new set of jet shape observables for track- based jets in central Pb-Pb collisions at √sNN = 2.76 TeV. The set of jet shapes includes the first radial moment or angularity, g, the momentum dispersion, pTD, and the differ- ence between the leading and sub-leading constituent track transverse momentum, LeSub. These observables provide complementary information on the jet fragmentation and can constrain different aspects of the theoretical description of jet-medium interactions. The jet shapes were measured for a small resolution parameter R = 0.2 and were fully co ...Daha fazlası

Transverse momentum spectra and nuclear modification factors of charged particles in pp, p-Pb and Pb-Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

We report the measured transverse momentum (pT) spectra of primary charged particles from pp, p-Pb and Pb-Pb collisions at a center-of-mass energy √sNN = 5.02 TeV in the kinematic range of 0.15 < pT < 50 GeV/c and |η| < 0.8. A significant improvement of systematic uncertainties motivated the reanalysis of data in pp and Pb-Pb collisions at √sNN = 2.76 TeV, as well as in p-Pb collisions at √sNN = 5.02 TeV, which is also presented. Spectra from Pb-Pb collisions are presented in nine centrality intervals and are compared to a reference spectrum from pp collisions scaled by the number of binary nu ...Daha fazlası

The effects of degassing, grain refinement & Sr-addition on melt quality-hot tear sensitivity relationships in cast A380 aluminum alloy

ULUDAĞ, Muhammet | ÇETİN, Remzi | DIŞPINAR, Derya | TİRYAKİOĞLU, Murat

Hot tearing tendency of A380 with various element additions (Sr, Sr+Ti, Ti, B and B+Sr) was investigated. Constrained rod casting (CRC) hot tearing test method was used to characterize the hot tearing sensitivity. Reduced pressure test (RPT) samples were produced from each condition and all trials were repeated three times. Number density of pores on the cross section of RPT samples was calculated via digital image processing and statistical analysis was carried out. Microstructure analysis was carried out to observe the effect of alloying elements. Hot torn cross sections were subjected to SE ...Daha fazlası

Neuroprotective Effects Of High-Dose Human Albumin Against Traumatic Spinal Cord İnjury in Rats

YILDIRIM, Timur | OKUTAN, Özerk | AKPINAR, Elif | YILMAZ, Ali | IŞIK, Hasan Serdar

BACKGROUND AND OBJECTIVES: Human serum albumin (HA) is a unique multifunctional protein with neuroprotective properties. We aimed to delineate the mechanisms of HA-induced neuroprotection, supresses inflammatory response and lipid peroxidation after spinal cord injury (SCI). METHODS AND STUDY DESIGN: Adult female Wistar rats weighing 210-250 g were used for the study. The rats were randomly and blindly allocated into five groups. The one-way analysis of variance (ANOVA) for parametric data and Shapiro-Wilk test was used for evaluating the normal distribution of the variables. Kruskal-Wallis fo ...Daha fazlası

Is Hypnosis Innocent? Physiopathological Evaluation of Effect on Vital Findings

SUNAR, Füsun | KÜÇÇÜKTÜRK, Serkan

Aim: Hypnosis is used in Complementary Medical Treatments. Our aim is to assess whether hypnosis is a side effect by evaluating effect in vital signs. Vital signs change in pathologic conditions. Fever, pulse, blood pressure and number of breaths is a good indicator of side effect evaluation. Methods: Healtly Twelve volunteers, six women and six men aged between 18 - 65 years who had received the necessary permits and consent. The hypnosis room was quiet and at room temperature to minimize the effect of vital signs. Participants used rapid hypnosis technique. Measurements were made under the h ...Daha fazlası

KIVRAK, Arif | YILDIZ, Hüseyin Bekir | GÖKYER, Selahattin | ÇARBAŞ, Buket

A novel alkoxy-bridged dithieno (3, 2-B:2’,3’-D) pyrrole (DTP) derivative was synthesized and its corresponding polymer poly(1,2-bis(2-(4H-dithieno[3,2-b:2’,3’-d]pyrrol-4-yl)ethoxy)ethane) (P(DTP-alkoxy-DTP)) was successfully obtained electrochemically. The e ff ects of alkoxy bridge in the structure on the electrochemical and spectroelectrochemical properties of the polymer were also investigated in detail. The results showed that the polymer fi lm exhibits multielectrochromic behavior and a low band gap of 1.82 eV.

The effects of aflatoxin B1 on growth hormone regulated gene-1 and interaction between DNA and aflatoxin B1 in broiler chickens during hatching

GÜLBAHÇE MUTLU, Elif | ARSLAN, Emine | ÖZNURLU, Yasemin | ÖZPARLAK, Haluk

Many types of aflatoxin cause problems for both public and animal health. Aflatoxin B1 (AFB1) is the most toxic and commonly encountered fungal toxin that appears in poultry feed and in feeds stored under unsuitable conditions. AFB1 decreases feed quality, egg production and fertility of hatching eggs. Also, AFB1 alters the development of embryos by infecting eggs. We investigated using sequence analysis the changes caused by different concentrations of AFB1 on the promoter sequences of the growth hormone regulated gene-1 (GHRG-1) in chick embryo at 13, 17, 19 and 21 days incubation.
